Abstract


Pemberian kompos pada tanah dapat memperbaiki sifat fisik tanah seperti pembentukan agregat atau granulasi tanah serta meningkatkan permiabilitas dan porositas tanah. Karena itu, peningkatan produktivitas padi perlu dipacu dengan penambahan bahan organik seperti kompos jerami. Penelitian menggunakan 9 kotak kompos dengan menggunakan bahan jerami padi. Jerami padi diambil dari daerah Tampalla Kecamatan Bone-bone  Kabupaten Luwu Utara, Indonesia. Penelitian dilakukan dalam bentuk eksperimen dengan Rancangan Acak Kelompok, tiga kali ulangan dan tiga perlakuan. Perlakuan biodekomposer (B), terdiri dari Tanpa Biodekomposer (B0), Promi (B1) dan EM-4 (B3). Pengambilan contoh kompos pada akhir percobaan ketika kompos dianggap telah matang untuk analisis sifat kimia serta kandungan senyawa organik. Pemberian biodekomposer promi dan EM4 pada proses pengomposan limbah jerami padi dapat meningkatkan laju pengomposan. Hal ini dapat dilihat dari parameter penurunan suhu (proses pematangan) yang lebih cepat dibanding kontrol, rasio C/N yang memiliki nilai lebih rendah dibanding kontrol, dan kadar unsur hara lebih tinggi dibanding kontrol
